4. We wound 20 turns of 10-guage wire on each transformer. That's just about how much wire would fit into the available space. It took a little ove...

5. It's a pretty simple circuit. In fact there's nothing in it except wire! We'll take two transformers and wind low-voltage secondary windings on...

6. Why do we use two transformers? Just one of these isn't big enough to make a really juicy welder.If you happen to find a big enough transformer...

7. Get out yer voltmeter:Here's the test to make sure the secondaries are both pushing the same direction.Our two secondaries in series produce 38v...
